Reviews of OEM Volkswagen AC condenser

I have a 2019 Atlas Highline. About 95,000 kms on it. Only major problem has been a/c condenser. Replaced under factory extended warranty. Other than that, no issues. Love the car.

During the rebuilt I installed a new condenser, new O-rings, new accumulator (drier), new orifice tube w/ new O-rings. Then I vacuumed down the AC system for half a day and since it was holding vacuum fine I recharged it with straight R134a (no sealer chemicals). It seemed to work fine in the beginning but that was when it wasn\u2019t that hot outside and now in the summer heat I can tell that something is not working right. The symptoms are usually delayed cooling by up to 15 minutes and even then it seems to cool for a while and then blows warm again.
